Window Message For Slider on Scroll Bar of List Box
In my application I have a list box with a horizontal scroll bar. I am trying to get some column headings to move ( which a in another list box) when the user clicks onto the scroll bar. Although I can get this to work when the user clicks on the arrow on scroll bar, it's not working when the user moves the bar on the scroll bar. Is anyone aware of a window message, which is sent when the user moves the bar on the scroll bar ?
